bring up both coolterm and Xojo Project so both running and disconnected from any port.

Modifications are to add a button that writes to the serial port a line and removes the if statements from serial port data available so that it logs everything coming back Xojo project to test with is a slightly modified version of the example program for communications with a barcode reader. No, the thing does get an error if there is something else with the port open. Xojo should be able to do it too but it (and I) must be missing something in the connection. There is NO data coming into DataAvailable at all (never fires).įWIW: I get this same behaviour with VS2017 VB.NET and I thought I check this with something simpler than that.Īnyone got any ideas on what this could possibly be? This isn’t hard. I connect to COM9 (9600,8,N,1 no flow) with no errors given Using the serial port example in Xojo 2018R4 that is looking for CRLF lines coming back from a barcode reader and putting them on the screen (sorry, wasn’t paying enough attention when I opened it as to what the name of it was, but it was under the communications dropdown of examples): I see all this traffic with TeraTerm without problems. The device is spitting out a couple of bytes with a CRLF at the end of it 2/second so this isn’t exactly fast or rocket science stuff. If I open it with TeraTerm, 9600,8,N,1 no flow control, I get bidirectional communications without problems. I’ve got a USB device that is presenting a virtual serial port on my windows machine.
